' The mechanism for carrying the cutting elements is illustrated as consistmg of a.

parallel disposed pair offrame members 11, preferably of cylindrical formation carried byand extending outwardly from thebody 1 i as in the drawing, the same being braced by truss rods 12 passing over struts 13, extend ing upwardly from the forward portion of thebody'l. The horizontal frame members q11 mount a tubularcross head 12, which is jslidable longitudinallythereof and said cross head serves as a supportand guide for a pair of tubular vertically disposed frame members .13, which' are. vertically slidable through I guide openings in the cross head.

operation of the apparatus it is essential In the that the cross head 12 be moved to any desirable position throughout the length ofthe members 11 and to accomplishithis I illustrate a hydraulic mechanism consisting of a cylinder 14 carried by the body land Q disposed parallel with the members 11 and Within the same operatesa piston 15 connected at its outer end with the cross head I "12. ,Fluid, pipes 16 extending from a valve casing 17 convey fluid under pressure into the cylinder 14 on opposite sidesof the piston,'dependent on the-position of the controlling valve 18. Fluid under pressure is admitted into the valve casing 17 through "pipe 19, leading from a fluid containing pressure tank 20 mounting an expansion dome 21. A pipe 22 leading from a pump [.23 operated by a motor 24: supplies fluid under pressure from a container 25 to the tank 20 and the'operation of the pump maintains the fluid under the desiredworking pressure. Dependent on the position of the valve 18 the pipes 16 are alternately converted into pressureand relief pipes'dependent on the direction of operation of the piston 15 and under all conditions when one pipe is applied as a pressure the other is utilized as a relief pipe and the fluid passingtherethrough is discharged into the container 25. It is desirable to releasably lock the cross' head 12 in its adjusted position on the frame members 11 and to accomplish this I provide a notched locking rod 26 extending from the body 1, passing over the cross head 12 and supported at its outer end .on the member 27 a which connects the free ends of the framevmembers 11. A

slotted lock casing 27 is carried by the cross head 12' and through thesa'me extends the member 26, the lock casing 27 carrying a locking'pin 28 adapted for selective reception within the member 26 throughout its, length.

The verticallydisposed tubular members 13 are connected at their lower end by a cutter supporting frame 29 and to reciprocate the same in unison within the crosshead 12 I. provide apiston 30, the rod of which connects with the member 29 and said piston reciprocates within I a vertically disposed cylinder 31,.fcarried by the cross head "12' between the members 13. v To' relatively lock the frame 29 at the desired height, I'feimploy a duplicate of the construction described above for releasably locking the cross-head 12 in position on the frame members 11,"

and I designate the duplicated elementsby the same reference characters with the ad 29 and at its upper end to the upperend of one'of the verticalframe members 13., To admit fluid under pressure to. the opposite .dition of a prime markQ The notched rod 26 connects at itslower end with the frame ends of the cylinder 31 to raise or lowerthe 5 piston 30, therein, Ifconnect with the oppo: site ends of the cylinder, fluid conducting pipes 32, a portion of each of which extends parallel with the rod or piston 15 and said pipes are slidably mounted within larger fixed pipes 33 through glands 34, the first pipes being carried by the body 1' and the pipes 32 being mounted to movewith the cross head 12. The pipes 33 connect with the valve casing 3 1 within which is mounted a valve 35, said casing being supplied with fluid under pressure from'tank 2O by.a pipe 36, a relief pipe 37 extending fromthe valvecasing 34 and discharginginto the container 25.

The position of the valve 35 when in the casing 34 controls the passage offfluid throughpipes 32 and 33 and causes a raising trolled by the respective valves 18 and 35,

The frame 72 carries a pivoted arm 75 overlying the cylinder 68 of that part of the formation extendingandzthe same is'connected at its end through "a slotted fulcrum 7 6 with a vertically disos ed reci arocatin arm 77 movable throu h face of the naturaldeposit. oted arm 75 is p1votally connected'an oper- -a guide 78 and on its lower end carryinga 1 motor 7 9 conventionally illustrated, the I armature shaft of the 'motor supporting a saw 80 for forming the vertical kerf in the WVith the pivat -ng arm 81,..its lower-end supporting guide =pins'82 receivable within the cam guides 88 =formed in the opposite faces of the remov- "able block 8 1 carried by a main plate 85.

The longitudinal movement of the frame 72 on guides'fl caused by the rotation of the cylinder 68 causes a relative movement of the p ns SQ'in'thecam guide 83, and this operationcausesthe vertical reciprocation of I z the member 80 to form a' vertical kerf in the I face of the natural deposit.

7 Thus it will'be observed'that the cam groove 69 with its connecting member 70 controls the movement ,7 j. of the'cutting member in the direction of movement of the main car iageand the }cam groove83 controls the vertical movement of the cutting member 80 in the clirection at right angles with the movement of themain carriage. It will be observed that the member 84 is removable from the main supporting plate 85, this admitting of the employment of grooved plates wherein the groove is v.of any desired pitch to vary the "vertical throw 'ofthe cutting member 80 whereby the same will cut a: depth corresponding with the thickness of one or anum- "her of bricks, the cam groove 83 illustrated being of a throw-only sufficient to cut one brick. At the commencement of the operationof the kerf forming members' in the face of the natural deposit to cut successive tiers of bricks or blocks therefrom, i-t is desirable to have the vertical kerfs of. succeeding tiers or layersregister, and to facilitate this registering without varying the operaby a stationarymember S'T-and cooperating 1 with the plate 85, this adjustment moving the plate 85 to and from the plate 87, which movement carries the cylinder 68 therewith, lineal movement of the cylinder relative to "shaft 67 being; accomplished by the sliding -connection 88, Fig. 12, between the cylinder direction to. cutfanother tier of blocks.

shaft and the shaft 67. The construction and operation of the invention will be under stood from the foregoing description and the operation, in brief, is as follows:

Assummg that the face of the formation that is to be operated on extends at a right angle to the plane ofthe saw 80at the top of Fig. 1 and that vertical-:kerfs havebeen already cut by the saw 80 in-the-upperface from the saw 80 to the saws 51,,the frame 1 will be driven forward, or-toward the top of the sheet containing Fig. -1,' thus causing the saws 51 to continuously operate to cut horizontal kerfs intersecting the vertical kei'fs previously made by the saw 80. Assum ng that the saw 80 has just been re- .tracted out of the last kerf that it has cut, the pins 82 willride in the horizontal limb of the cam grooves 83, thus maintaining the saw 80 in retracted position for an interval of time. During this interval of time the slide 74: Wlll ride inthe channel 70, thus causing the frame 72 to travel in the same direction as, the frame 1 and sufficiently faster than said frame llto position the saw 80 the length of a block ahead. of its last kerf. Then: the pins 82 will ridein the descending limb of the cam grooves 83 'to'cause the saw 80 to make another out and while said saw 80 is making its out, the groove v69 Will-engage the slide 74, thus causing theframe 72 to travel, at thesame speed as the frame 1, butin the oppositedirection so that the saw 80 will not be subjected to translation relative to the formation while said saw is making its cut. At the finish of. the cut, the pins 82 will ride in the ascending limb of the cam grooves 83 to cause the saw 80 to be retracted from the cut and this occurs while the slide 7 1 is in the groove 69 so that translation of the saw -80'relative to the formation does not occur while the saw 80 is being retracted. The cycle just described is then repeated indefinitely until oneend of the area being operated on is reached. This completes the cutting of one tier of blocks.

The saw 80 will then be removed from the armature shaft on which it is mounted and said saw will be secured to the armature shaft of the other motor 79, and the saw 39 will be changedin the other shaft 38. 7 Then the operator will'properly manipulate-the valve 35 to. lower the cutter-supporting frame 29 sufficiently to bring the saws into a position for cutting another tier of blocks, and the frame 1 will be driven inthe reverse The apparatus will be thus adjusted at each end of the travel of the frame 1 and successive tiers of blocks cut to the lowest level to which the saw-supporting frame 29 can be lowered,

thus cutting off a complete layer of the formation into blocks. Thegoperator will then properly .manipulatethe .val'veslS, 35 to an a cut into blocks.
